  • Article

The PCI_EXPRESS_ROOT_ERROR_STATUS structure describes a PCI Express (PCIe) root error status register of a PCIe advanced error reporting capability structure.

Syntax

typedef union _PCI_EXPRESS_ROOT_ERROR_STATUS {
  struct {
    ULONG CorrectableErrorReceived : 1;
    ULONG MultipleCorrectableErrorsReceived : 1;
    ULONG UncorrectableErrorReceived : 1;
    ULONG MultipleUncorrectableErrorsReceived : 1;
    ULONG FirstUncorrectableFatal : 1;
    ULONG NonFatalErrorMessagesReceived : 1;
    ULONG FatalErrorMessagesReceived : 1;
    ULONG Reserved : 20;
    ULONG AdvancedErrorInterruptMessageNumber : 5;
  } DUMMYSTRUCTNAME;
  ULONG  AsULONG;
} PCI_EXPRESS_ROOT_ERROR_STATUS, *PPCI_EXPRESS_ROOT_ERROR_STATUS;

Members

DUMMYSTRUCTNAME

The DUMMYSTRUCTNAME structure.

DUMMYSTRUCTNAME.CorrectableErrorReceived

A single bit that indicates that a correctable error message has been received.

DUMMYSTRUCTNAME.MultipleCorrectableErrorsReceived

A single bit that indicates that multiple correctable error messages have been received.

DUMMYSTRUCTNAME.UncorrectableErrorReceived

A single bit that indicates that an uncorrectable error message has been received.

DUMMYSTRUCTNAME.MultipleUncorrectableErrorsReceived

A single bit that indicates that multiple uncorrectable error messages have been received.

DUMMYSTRUCTNAME.FirstUncorrectableFatal

A single bit that indicates that the first uncorrectable error message that was received was for a fatal error.

DUMMYSTRUCTNAME.NonFatalErrorMessagesReceived

A single bit that indicates that one or more non-fatal uncorrectable error messages have been received.

DUMMYSTRUCTNAME.FatalErrorMessagesReceived

A single bit that indicates that one or more non-fatal uncorrectable error messages have been received.

DUMMYSTRUCTNAME.Reserved

Reserved.

DUMMYSTRUCTNAME.AdvancedErrorInterruptMessageNumber

The MSI/MSI-X vector that is used for the interrupt messages that are generated in association with any of the status bits of the advanced error reporting capability.

AsULONG

A ULONG representation of the contents of the PCI_EXPRESS_ROOT_ERROR_STATUS structure.

Remarks

The PCI_EXPRESS_ROOT_ERROR_STATUS union is available in Windows Server 2008 and later versions of Windows.

A PCI_EXPRESS_ROOT_ERROR_STATUS union is contained in the PCI_EXPRESS_ROOTPORT_AER_CAPABILITY structure.
